NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Evaluation of Mobile App-derived Cardiorespiratory Fitness and Referral Patterns in Patients Participating in a Cardiac Rehabilitation Program: A Pilot Initiative
ABSTRACT
Background:
Cardiac rehabilitation is known to improve morbidity and mortality; however, it is underutilized.
Objective:
This pilot initiative will: 1) determine if a smartphone app is able to detect meaningful differences in cardiorespiratory fitness after participation in traditional cardiac rehabilitation, 2) observe cardiac rehabilitation referral patterns and 3) monitor patient engagement in cardiac rehabilitation.
Methods:
During February 2020, n = 34 patients were enrolled in outpatient phase II cardiac rehabilitation at our institution and included in the initiative. A mobile phone app, Heart Snapshot, was used to estimate VO2 max at baseline and after 4 weeks of participation in cardiac rehab. Providers were surveyed about referral patterns. The plan-do-check-act cycle was used to assess improvement.
Results:
The mean age was 67 (SD: 13) and ischemic heart disease was the main reason for referral. Improvement in app-derived VO2 max was positively correlated with improvement in METs. The survey revealed provider lack of understanding of conditions benefitting from cardiac rehabilitation and discrepancy regarding responsibility referring to cardiac rehabilitation.
Conclusions:
Cardiac rehabilitation is an important yet underutilized intervention. There is room for improvement in provider education and ownership for cardiac rehabilitation referrals. An app-based VO2 estimate may be a solution for remotely monitoring fitness improvement.
